My BFF since 5th grade and I just spent 4 days in San Antonio. We went to the Riverwalk, Witte Museum, Safari Park, the San Antonio Zoo, Natural BridgeCaverns, and Historic Gruene, TX.We had a great time everywhere we went, but for me the highligts were the Caverns, totally awesome! I've been to caverns in the Smokey Mountains, and toLuRay Cavern in Virginia, but this one was by far the best as far as the "wow!! factor goes"But the fish exhibits at the zoo were the highlights for me. They had lots of big tanks with Africans, but the Malawans were in a huge tank with a pair of hippos lounging in there with them. Assorted zebra species, peacocks, and haps...must have been hundreds of them, and some of them were enormous.The best thing was the hippo opened his mouth, and they swarmed inside to pick his teeth!I am going to try to post some pictures of this.
